Electric motors remain the number one source of electricity consumption
globally. With the vast majority of deployed motors commonly based on
outdated, inefficient technologies, the migration toward digital-based
control systems with secure networking capabilities presents a
significant opportunity for both energy conservation and end-product
feature innovation.

The Kinetis KV5x MCU addresses this by combining leading-edge processing
power, sophisticated analog and timing peripherals, and new
connectivity, security and safety features. It brings increased motor
efficiency, remote system management and end-node interoperability via
the Internet of Things (IoT) to a vast range of applications, from home
appliances to complex industrial drives.

The Kinetis KV5x MCU incorporates an IEEE® 1588 Ethernet controller, a
cryptographic acceleration unit with random number generator and a
memory protection unit. With motors often employed in safety-critical
environments such as manufacturing process control, these features allow
developers to implement new services via the IoT infrastructure while
protecting against erroneous inputs that could lead to an undesired
operating condition.

“In combining the advanced processing power of the ARM Cortex-M7 core
with Freescale’s market-leading IP and robust connectivity, security and
safety features, the Kinetis KV5x MCU is establishing the motor control
and power conversion segments as compelling new additions to the vibrant
IoT landscape,” said Geoff Lees, senior vice president and general
manager for Freescale’s microcontroller group. “Kinetis KV5x customers
can look forward to a new era of connected industrial applications
featuring new levels of performance, reliability and power efficiency.”

The KV5x features a 240 MHz ARM Cortex-M7 core with single precision
floating-point unit. This executes program code from up to 1 MB of
on-chip flash memory via a 256-bit wide interface that minimizes CPU
wait states. 128 KB of data tightly coupled memory (DTCM) and 64 KB of
instruction TCM (ITCM) maximize high performance deterministic
processing, ensuring optimum response for real-time motor speed and
position detection. And with four high-speed 12-bit ADCs, each capable
of 5 Msps, the Kinetis KV5x MCU family can support fully asynchronous,
dual 3-phase motor control with two dedicated ADCs and 8 channel PWMs
per motor. Dual 12-channel eFlexPWMs also support 312 picosecond
resolution for driving up to 8 half-bridge power stages in power
conversion applications.

“Freescale’s new Kinetis family is taking a leading role in unlocking
new areas where energy efficiency and connectivity can enable
innovation, in this instance moving motor control beyond its traditional
boundaries,” said Noel Hurley, general manager for ARM’s CPU group. “The
latest energy-efficient Cortex-M7 is a good fit for this market with its
enhanced DSP capability and support for safety-critical applications.”

Coinciding with the introduction of the new Kinetis KV5x MCU family,
Freescale is also launching several additions to its growing motor
control and digital power conversion enablement portfolio:

FRDM-KV10Z, FRDM-KV31F and FRDM-MC-LVBLDC/PMSM – Low-cost Freescale
Freedom development platforms for BLDC and PMSM motor control. See
them on display at embedded world 2015. Production planned for Q2 2015.

Programming for Kinetis MCUs is available for all Kinetis V series
products - a service for customers who wish to have their unique
software programmed onto their MCUs prior to shipment. For more details,
